IMPROVEMENT IN MACHINES FOR MAKING WASH-BOILERS.

Specification forming part of Letters Patent No. 155,907, dated October13, 1874; application filed April 3, 1873.

To all whom it may concern Be it known that we, JAMES E. WELLS, of NewMilford, in the county of New Haven, Connecticut, and GEORGE W. BENTLEY,of Brooklyn, in the county of Kings, New York, have invented, made, andapplied to use an Improved Machine for the Manufacture of Wash- Boilers;and that the following is a full, clear, and correct description of thesame, reference being had to the accompanying drawing, making part ofthis specification, and to the letters of reference marked thereon, inwhich- Figure I is a side elevation of our invention. Fig. II is a topview of the same. Fig. III is an end View of the same. Fig. IV is atransverse section of the same, showing the cam governing the positionof the frame K.

In the drawing like parts of the invention are designated by the sameletters of reference.

The nature of the present invention consists in the construction, asmore fully hereinafter set forth, of an improved machine for themanufacture of wash-boilers; the object of the invention being .theconstruction of a machine by which the operations of setting in thebottom into the body of the wash-boiler, and wiring the top of theboiler, shall be expeditiously and cheaply done.

To enable those skilled in the arts to make and use our invention, thefollowing description will be sufficient.

A shows the frame of the machine, serving to support its operativeparts. B is the main or driving shaft, inserted in boxes in the frame A,and having keyed upon it a pinion, 0, gearin g into the cog-wheels D andD. D is a cogwheel keyed upon a shaft, E, inserted in boxes in the frameA, and on the opposite end of this shaft is secured the cam F. D is acog- Wheel keyed upon the shaft G, inserted in boxes in the frame A.Upon this shaft G is secured a head or form, H, one portion of which isprovided with the teeth I, as shown, and upon this shaft G are securedthe forming-heads J. K shows a secondary frame attached to the lever L,which lever L is attached, in turn, to an upright, M, swiveled at itslower end to the standard N, and provided with a stud and roller, 0,playing in the cam F. P shows a flat spring, attached at its lower endto the frame A, while its upper end bears against the upright M. Theframe K is provided with the hangers Q, which hangers support the shaftR, and also the shafts S and T. Upon the shaft R are secured the facedroller U, pro vided with gearing engaging with the gearing upon the formH, the pinion V gearing into a pinion, W, secured upon the shaft S, theheads or rolls X X having a bearing upon the forming-heads J, and thepinion Y gearing into the pinion Z upon the shaft T. Upon the shaft S isalso placed a roll, 1, and upon the shaft T is placed the roll 2.Attached to an eye secured in the frame K is one end of the belt orchain 3, the opposite end of which is attached to the bar 4, swiveled.at one end to the frame A. 5 shows pulley attached to the frame A, overwhich the belt or chain passes. The object of the belt or chain and baris to enable the operator to elevate the frame K, when desired, bydepressing the forward end of the bar 4.

Such being the construction, the operation is as follows: The frame K iselevated by the operator by depressing the forward end of the bar 4, towhich is attached one end of the belt or chain 3, the opposite end ofthe same being attached to the frame K, so that, as the bar 4 isdepressed, the belt or chain 3 is drawn down with the bar, and the frameK is raised. The body of the wash-boiler, which is formed of a sectionof a cylinder, is now placed by the operator upon the forming-head J,and the frame K is now lowered by relieving the hold upon the bar 4until the rolls X X shall bear upon the body of the wash-boiler. Motionis now communicated to the driving-shaft B,

'which, through the pinion O, secured upon it,

and gearing into the cog-wheels D and D as shown, causes the shafts Eand G to revolve. As the shaft E revolves it carries with it the cam F,and as the shaft G revolves it carries with it the head H. This head Hgears into the gearing upon the faced roller U upon the shaft R, andsets the same in motion, which, in turn, through the pinion V engagingwith the pinion W, operates the shaft S, and, through the pinion Ygearing into the pinion Z, operates the shaft T. With the body of theboiler in position upon the forming-heads J, the roll 2 upon the shaft Thaving a bearing upon the metal of which the same is composed at oneend, turns the metal out and up from the horizontal position into avertical, or nearly vertical, position, ready for the bottom of theboiler to be received. The frame K is now elevated, as alreadydescribed, and the machine is stopped that the bottom may be inserted inone end of the body of the boiler. The bottom having been inserted andthe frame K lowered, as al ready described, the machine is again set inmotion, and the roll X upon the shaft R bears upon the edge of thebottom, and'turns the same over the upturned or burred portion of thebody of the boiler. The body of the boiler and the bottom may now heslipped or adjusted in position upon the forming-heads J sufficiently togive the roll X a bearing upon itsentire lower edge within which thebottom is contained, and the motion of the machine continuing, theprojecting metal is flattened or set down to the boiler by this roll XDuring the operation just described the second operation of wiring thehead or upper portion of the boiler is also being performed. The rollerX is grooved and the roller 1 is filleted at one end, which filleted endis brought into line with the grooved roller by shifting the roller 1into position by the shifter 10, and, as the top end of the boiler isreceived between theiilleted roller 1 and the grooved roller X,

the metal is turned up and over andaro'und the Wire inserted betweenthese rollers, said operation arising from the metal being receivedbetween the fillet and groove in the rollers. This completes theopera-tion. and, the machine having been stopped, the boiler may beremoved.

During the operations just recited the cam F has caused the frame K,with its adjuncts, to maintain a proper position relatively to the headsJ for the operation of the machine.

It will be seen that by the employment of the machine boilers can beexpeditiously made, and that the cost-of such manufacture is greatlyreduced, while uniformity of manufacture is secured.

Having now set forth our invention, what we claiin'as new is-- 1. Thecombination of the forming-heads J with the geared head H, and the frameK, provided with the rolls X X and rolls 2 and 1, when the same shall beconstructed and operated substantially as and for the purposes setforth.

2. The combination, with the frame K, of the lever L, swiveled uprightM, cam F, and belt 3, and bar 4, substantially as and for the purposesdescribed.
